Dirt Bike Exhaust Pipe Dent Remover

09-20-2012, 09:25 PM

Two stroke dirt bike exhaust pipes are constantly getting dented. They are usually paper thin so just about any kind of rock, log or knee will dent them.
There are a few methods on removing the dents of which I have tried a few over the years.
This project is the pressure and heat system.
The ali members cost $12.00 including cutting.
Then it was just drilling, tapping and Tigging.

I finally had some time and a few pipes that needed some love. With the dent remover attached and set at 40psi I heated the dent area with map gas. A few minutes later all gone. This fix is not the best due to the dent was on a welded seem. Still a pretty good result.

On the end of bike pipes is a flange make sure the three fixing bolts are fixed below the flange so the yoke will not fly off when pressurised. With the three bolts try your best to centre the pipe and make sure an amount of the pipe protrudes past the yoke.

Before you pressurise the pipe make sure you point the caps away from people, animals and property. With the compressed air hose attached and the ball valve in the closed position slowly open the ball valve paying attention to the gauge. Do not allow the pressure to exceed 40psi. When the heat is applied the internal pressure will rise naturally to around 60psi. If there is an air leak at the seals that is not large that is okay as your compressor will keep the internal pressure at 40psi. it there is a large leak go back and start again.

Make sure before applying the heat that all paints and surface treatments have been removed. Apply Map gas to the ridge of the dent in a circular motion. Again make sure the caps are pointing away from anything that could be hurt or killed, this is like a gun and should only be pointed down range. As the pipe heats to a red colour you will see the pipe pop. It is very sutle.
